.7b (All, 11171/0711, /l/V 'mln/y cm1/cern:

lie it known that l, ltussnLL l). BaANsoN, a citizen of the UnitedStates, residing at Ridgeville, in the county of Randolph, State oflndiana, have invented certain new and useful .improvements in Books;and l do hereby declare the following to be a full, clear, and exactdescription of the invention,such as will enable others skilled in theart to which it appertains to make and use the same.

llhis invention relates to books, and more particularly to the bindingthereof, and has for its object to provide a book so arranged that thebinding' may be removed from the leaves and attached to other leaveswhen desired, it being understood that the invention is especiallyadapted for blank-books, in which the leaves are useless after beinglilled.

@ther objects and advantages will be apparent from thefollowingdescription, and it will be understood that modifications ofthe speciiic construction shown may be made and any suitable materialsmay be used without departing from the spirit of the invention.

ln the drawings forming a portion of this speciiication, and in whichlike characters of reference indicate similar parts in the severalviews, Figure 1 is a perspective view of the book. Fig. 2 is a sectionalview. Fig. 3 is a sectional view showing a modification in which thescrews are inserted from the outside of the covers. Fig. et is aperspective view showing a modified form in which the movable plates arehing'ed. Fig. 5 is adetail sectional view of the plates. Fig. 6 is adetail sectional view of the plates shown in Fig. 4t.

Referring now to the drawings, there is shownabook comprising aplurality of leaves 5, secured together in the usual manner and havingfastened to their rearward edges a strip of strong fabric 6, whichextends 'be' youd the outer leaves, as shown.

i `he binding of the book consists of the usual back 8, to which thecovers 9 and 10 are secured at their rearward edges, and in the presentinvention the covers are provided with recesses 11 in their inner facesat their rearward edges., and extending from end to end thereof anddisposed in these recesses are metallic plates 1Q, which in thicknessare equal to substantially half the depth of the recesses, and theseplates l2 are provided with longitudinal grooves 13 for a purpose to bepresently described. The plates 12 are secured to the covers by means ofiiat-headed screws la, and each plate is provided with a longitudinally-arranged series of threaded perfor-ations 15. When in use, the leaves 5are disposed in the binding in the usual manner, and the free edgeportions of the fabric 6 are disposed upon the plates 12, the fabricshaving' Openings 16 therethrough, which aline with the perforations 15,and disposed upon the fabrics are metallic plates 17, which are securedin position by means of flat-headed machine-screws 18, which are passedthrough perfor-ations 19 therein and have their lower ends engaged inthe perforations 15. The plates 17 are provided with longitudinal ribs20, which register with the grooves 13 and force the fabric 6 thereintowhen the screws are tightened, thus preventing loosening of the leaves,and when the plates 17 are in position they lie lflush with the innerfaces of the covers 9 and 10. As will be readily understood, the plates17 may be removed to permit of the removal of the leaves 5 and thesubstitution of other leaves therefor. lt will thus be seen that abinding is provided which not only possesses the feature of beingremovable, but forms a heavy and substantial binding which is extremelysimple and which may be manufactured at a low cost.

In Fig. 3 the covers are provided with the plates 12, which, asdescribed, lie j ust beneath the outer surfaces of the covers. In thisform the covers are provided with openings A, which aline with theperforations of the plates, these perforations in the present instancebeing unthreaded. The plates 17 have their perforations provided withthreads, and the screws 18 are inserted from the outer faces of thecovers.

In Fig. i there is shown a construction in which the plates 17 arehinged to the plates 12, as shown at B, and in this case bolts C areengaged in the openings of the plates 12 and project beyond the innerfaces thereof for engagement in the openings of the plates 17 IOO whenthese plates are moved to lie against the ward edges, plates secured inthe recesses, 25

plates l2. The fabric 6 of the leaves is engaged between the plates, theplates being' held with the fabric clamped therebetween b y means ofnuts D, which are engaged with the bolts C.

It will of course be understoood that the plates in the modified formsmay be provided with cooperating projections and depressions, as in thefirst-described form.

Vhat is claimed is l. In a book, the combination with leaves providedwith tabs, of a binding therefor, said binding comprising covers and aconnectingbacl, said covers having recesses in their inner faces attheir'rearward edges, plates secured in the recesses, other platesdisposed against the lirst-named plates, and attaching' devices engagedin the two plates to hold them together, the tabs of the leaves beingdisposed between the plates of each pair.

2. A boohv comprising' a binding including covers and aconnecting-back,said covers having recesses in their inner faces attheir rearother plates disposed in the recesses and removably attachedto the first-named plates and a plurality of leaves disposed between thecovers and having tabs removably secured between the plates of eachpair.

3. A book comprising a binding including two covers and aconnecting-back, said covers having' recesses therein at their rearwardedges, plates secured in the recesses and having depressions therein,other plates disposed within the recesses and detachably secured to theiirst-named plates, and having projections thereon engaging thedepressions of the tirstnamed plates, and a plurality of leaves disposedbetween the covers and having tabs engaged between the plates.

ln testimony whereof I afliX my signature in presence of two witnesses.

RUSSELL P. BRANSON.
